Test 1
For the first test, are there things we should know going into the test that is not given to us? This can range from different formulas to conversions or anything else.

Re: Test 1
Pretty much all of the formulas and conversions are given. You should know the following relationships:
pOH + pH = pKw
[OH][H30] = Kw
(Ka)(Kb) = Kw
pKa + pKb = pKw
PV = nRT
If you know these then you should be good.

Re: Test 1
You can consult the Constants and Equations sheet on Dr. Lavelle's website too! It's pretty handy to use while you do your homework so that you're used to it when taking tests:

They usually provide all the equations you need to know. I find it best to look at it before the test so you are familiar where everything is.

Re: Test 1
If pOH and pH always add up to 14, is it possible to have a negative pH? What about a pH higher than 14?

Re: Test 1
While it is possible to have a negative pH or a pH that is above 14, for the purpose of this class, we are only considering phs of 0-14.
Hope this helps.
